課題來源
DC tall是該廠根據(jù)市場需求開發(fā)研制的電池柜冷藏箱。電池柜冷藏箱（DC tall）的主要結(jié)構(gòu)采用的是鈑金材料，本產(chǎn)品的主要研究目的：將電池保持一定的溫度，使得電池延長使用壽命。裝電池后產(chǎn)品重量達(dá)1.42t吊起時頂部的四個螺絲每個都必須能承受220kg的拉力。保持電池柜內(nèi)部溫度251，并保持內(nèi)部溫度的均勻性
科學(xué)依據(jù)（包括課題的科學(xué)意義；國內(nèi)外研究概況、水平和發(fā)展趨勢；應(yīng)用前景等）
電池柜冷藏箱DC Tall之箱體主要零件部件的計算設(shè)計研究的意義將電池保持一定的溫度，使得電池延長使用壽命，節(jié)能減排、綠色成本、節(jié)約成本。
模具工業(yè)是國民經(jīng)濟的基礎(chǔ)產(chǎn)業(yè)，據(jù)統(tǒng)計，金屬零件粗加工的75%、精加工的50%和塑料零件的90%是用模具加工完成的。被譽為“工業(yè)之母”、“皇冠工業(yè)”的模具制造業(yè)是高技術(shù)密集型產(chǎn)業(yè)，模具工業(yè)一稱為先進(jìn)制造技術(shù)的重要組成部分。模具工業(yè)的發(fā)展水平標(biāo)志著一個國家工業(yè)水平及產(chǎn)品開發(fā)能力。
其中，沖壓是模具工業(yè)中最重要的加工方法之一。沖壓的應(yīng)用范圍十分廣泛，據(jù)統(tǒng)計在電子產(chǎn)品中，沖壓件（包括鈑金件）的數(shù)量約占零件總數(shù)的85%，在全世界的鋼材中，有60%-70%是板材，其中大部分是經(jīng)過沖壓制成成品。沖壓加工在汽車、拖拉機、點擊、儀器儀表、家用電器、自行車、辦公機械等機械工業(yè)和國防工業(yè)以及日常生活用品的生產(chǎn)方面，占據(jù)著十分重要的地位。
本課題要求對自己選定的零件進(jìn)行沖壓模設(shè)計。通過對零件進(jìn)行詳細(xì)的工藝分析確定零件的沖壓工藝方案并制定部分零件的制造工藝。通過本課題，可以培養(yǎng)我們綜合運用所學(xué)的基礎(chǔ)理論、基本知識和基本技能來分析、解決實際問題的能力和初步進(jìn)行科學(xué)研究的；培養(yǎng)我們獨立工作的能力、創(chuàng)新能力以及理論聯(lián)系實際和嚴(yán)謹(jǐn)求實的工作作風(fēng)的重要途徑。
我國沖壓模具產(chǎn)品的質(zhì)量和生產(chǎn)工藝水平，總體上比國際先進(jìn)水平低許多，而模具生產(chǎn)周期卻要比國際先進(jìn)水平長許多。產(chǎn)品質(zhì)量水平低主要表現(xiàn)在精度、表面粗糙度、壽命及模具的復(fù)雜程度上；生產(chǎn)工藝水平低則主要表現(xiàn)在加工工藝、加工裝備等方面。模具壽命也只有國際先進(jìn)水平的50%左右，大型、精密、技術(shù)含量高的轎車覆蓋件沖壓模具和精密沖裁模具，每年都要花費大量資金進(jìn)口。但現(xiàn)在一汽模具公司、東汽模具公司、上海大眾模具公司等中國沖壓模具業(yè)的龍頭企業(yè)可部分生產(chǎn)此類模具。但是在一些低檔次的簡單沖模，則已供過于求，市場競爭非常激烈。
發(fā)展趨勢
模具技術(shù)的發(fā)展是模具工業(yè)發(fā)展最關(guān)鍵的一個因素，其發(fā)展方向應(yīng)該為適應(yīng)模具產(chǎn)品“交貨期短”、“精度高”、“質(zhì)量好”和“價格低”的要求服務(wù)。未來，我國模具工業(yè)和技術(shù) 2 主要發(fā)展方向?qū)⒅饕性谝韵聨讉€方面：

擬采取的研究方法、技術(shù)路線、實驗方案及可行性分析
研究的基本內(nèi)容，擬解決的主要問題
本課題研究的是墊圈沖壓模具設(shè)計，要求其材料軟黃銅H62，采用大批量生產(chǎn)，精度要求高。通過合理的設(shè)計凸凹模，選擇合理的標(biāo)準(zhǔn)模架，制造出符合要求的制件。 （1）查閱有關(guān)模具設(shè)計方面的資料，翻譯與模具設(shè)計相關(guān)的英文文獻(xiàn)；

可能存在的問題
（1）沖孔時要保證斷面質(zhì)量、尺寸精度和形狀誤差。
（2）合理的安排工序的先后順序及一模多腔的位置分布。
（3）沖裁間隙值對沖裁件質(zhì)量、沖裁力及模具壽命有很大影響，是沖裁工藝及沖裁模具設(shè)計的重要工藝參數(shù)。間隙大小合適則可得到好的斷面質(zhì)量；同時刃口銳利也可得到好的斷面質(zhì)量。得到的沖裁件精度質(zhì)量高，即零件的實際尺寸和沖裁模工作部分的尺寸之間的偏差少。
（4） 凸凹模刃口會有磨損，這樣會影響斷面質(zhì)量，應(yīng)及時更換刃口。
（5） 設(shè)計前后工序的關(guān)聯(lián)性以及模具的關(guān)聯(lián)性，合理安排工序，盡量是模具的結(jié)構(gòu)緊密，同時在模具的設(shè)計過程中環(huán)要考慮到所設(shè)計的零件的可加工性，要盡量多的選用標(biāo)準(zhǔn)間，達(dá)到規(guī)范設(shè)計的要求成為此次畢業(yè)設(shè)計的難點

圖 1 Tool Control System for the
1) Electric Transmission horizontal rotary tool storage systems are the mechanical movements are repeated short-term work system. And the run-time system needs some speed, speed transmission needs, the system will use VVVF method can be used simple structure, reliable operation of the motor and frequency inverter.
2) Control of the system is divided into two kinds of manual control and automatic control, manual control as a general reserve and debugging methods of work; ways to the system control computer (IPC) and the control unit (inverter contactor , etc.) consisting of a control system.
3) location and positioning accuracy of the system automatically identify the site and location using a detection device as proximity switches, relays through the plate-point isolation and the number plate recorded close to the switching signal acquisition and operation of Hutchison with a Optimal Path addressable identify the current location and shelves of the purpose of the shelf location. In order to enable a more accurate positioning system, adopted two photoelectric switches, to detect the two shelves of the two films.
1.2.The functions of the knife
knife The is the role of reserves a certain number of tools, machine tool spindle in hand to achieve the fungibility a disc cutter knife is the type of library, the chain knives, and other means, in the form of the knife and capacity according to the Machine Tool to determine the scope of the process.
1.3.Common types
The knife is a tool storage devices, the common knife mainly in the following forms:
(1) the turret knife
Including the first level turret vertical turret and the first two, see Figure 2.6 a) and b):
(2) the disc cutter
Disc knife in the library with discoid knife, cutting tool along See how vertical arrangement (including radial and axial from knife from knife), along See how radial array into acute or arranged in the form of the knife. Simple, compact, more applications, but are ring-cutter, low utilization of space. Figure 2.7 a) to c). If the knife storage capacity must be increased to increase the diameter of the knife, then the moment of inertia also increased correspondingly, the election campaign long knife. Tool number not more than 32 general. Cutter was multi-loop order of the space utilization knife, but inevitably given the knife from complex institutions, applicable to the restricted space Machine Tool storage capacity and more occasions. Two-disc structure is two smaller capacity knife on both sides of the sub-spindle place, more compact layout, the number of certificates corresponding increase knife, apply to small and medium-sized processing center.
(3) the chain knife
? Including single-and multi-ring chain ring chain, chain link can take many forms change, see Figure 2.8 a) to c), the basic structure shown in Figure 2. 8 do
Features: knife apply to the larger capacity of the occasion, the space of the small number of generally applicable to the tool in the 30-120. Only increase the length of the chain tool will increase the number should not be increased circumferential speed of its moment of inertia of the knife does not increase the disc as large.
(4) linear combination knife and the knife library
The linear knife simple structure in Figure 2.9, tool single order, the capacity of small knife, used for CNC lathe and drill press on. Because the location of fixed knife, ATC completed action by the spindle without manipulator. The cutter knife is generally the turret combination turret with a combination of the disc cutter knife and the chain combination. Every single knife the knife certificates of smaller, faster tool change. There are also some intensive drum wheel, and the lattice-type magazine for the knife, the knife-intensive though. Small footprint, but because of structural constraints, basically not used for single processing center, the concentration used for FMS for the knife system.
1.4 Tool storage capacity
Tool storage capacity of the first to consider the needs of processing, from the use of point of view, generally 10 to 40 knives, knife will be the utilization of the high, and the structure is compact.
1.5 Tool options
(1) choose to order processing tool according to the order, followed Add to the knife every knife in the Block. Each tool change, the order of rotation of a cutter knife on location, and remove the need knives, has been used by the cutter knife can be returned to the original Block, can also order Add Block, a knife. However, as the knife in the tool in different processes can not be repeated use of the knife must increase the capacity and lower utilization rate.
(2) most of the arbitrary choice of the current system of using arbitrary NC election knives, divided into Daotao coding, coding and memory-cutter, three. Daotao coding tool code or knives or Daotao need to install the code used to identify, in accordance with the general principle of binary coding coding. Tool knife election coding method uses a special knife handle structure, and each of the coding tool. Each of the tool has its own code, thereby cutting tool can be in different processes repeatedly used, not to replace the tool back at the original knife, the knife capacity can be reduced accordingly. Memory-election this paper knife, in this way can knives and knife in the position corresponding to the Daotao memory of the PLC in the NC system, no matter which tool on the Inner knife, tool information is always there in mind, PLC . On the knife with position detection devices, will be the location of each Daotao. This tool can be removed and sent back to arbitrary. On the knife is also a mechanical origin, every election, the nearest knife selection.
1.6. Control of the knife
? (1) the knife as a system to control the positioning axis. In the ladder diagram in accordance with the instructions for computing T code comparison of the output angle and speed of instructions to the knife the knife servo drive servo motor. Tool storage capacity, rotation speed, and / deceleration time, and other system parameters can be set in such a manner free from any outside influence positioning accurate and reliable but the cost is higher.
? (2) knife from the hydraulic motor drives, fast / slow the points, with proximity switches count and positioning. In comparison ladder diagram of the current storage system knife (knife spindle) and goals knife (pre-knife) and computing, then output rotation instructions, judging by the shortest path rotation in place. This approach requires sufficient hydraulic power and electromagnetic valve knife the rotational speed can be adjusted through the throttle. But over time may be oily hydraulic, oil temperature and environmental factors impact the change in velocity and accuracy. Not generally used in large and medium-sized machine tool change frequently.
? (3) the knife from AC asynchronous motor driven cam mechanism (Markov institutions), with proximity switches count, which means stable operation, and generally accurate and reliable positioning cam used in conjunction with a mechanical hand, ATC fast-positioning.
2. ATC, the main types, characteristics, and the scope of application
2.1 Auto Rotary Tool
Rotary Tool automatically on the use of CNC machine tool is a simple installation of automatic tool change, the Quartet and 47.60 Turret Tool various forms, such as rotary turret were installed on four, six or more of the Tool , NC instructions by ATC. Rotary Tool has two vertical and horizontal, relatively simple structure, applicable to economic CNC lathe.
Rotary Tool in the structure must have good strength and stiffness, resistance to bear rough Cutting Tool in the cutting force and reduce the role of deformation and improve processing accuracy. Rotating Tool to choose reliable positioning programme structure and reasonable position, in order to ensure that each rotary turret to a higher position after repeated positioning accuracy (typically 0.001 to 0.005mm). Figure 2.1 shows the spiral movements of the Quartet Turret.
Auto Rotary Tool in the simplest of ATC, is 180 o rotary ATC devices, as shown in Figure 2.2 ATC instructions received, the machine control system put ATC spindle control to the designated location at the same time, the tool movement to the appropriate location, ATC, with the rotary axis and at the same time, the knives matching tool; drawbars from Spindle Cutting Tools rip, ATC, will be the tool from their position removed; ATC, 180 o rotary tool spindle and the tool and tool away; ATC, the Rotary At the same time, the tool refocusing its position to accept Spindle removed from the cutting tool; Next, ATC, will be replaced with the cutter knives were unloaded into the spindle and tool: Finally, back to the original ATC, "standby" position. At this point, ATC completed procedures to continue to run. This ATC, the main advantage of simple structure, the less movement, fast tool change. The main disadvantage is that knives must be kept in parallel with the axis of the plane, and after the home side compared to the tool, chip and liquid-cutting knife into the folder, it is necessary to the tool plus protection. Cone knife folder on the chip will cause ATC error, or even damage knife folders, and the possibility of spindle. Some processing centre at the transfer, and the tool side. When the ATC command is called, the transfer-cutter knives will be removed, the machine go forward, and positioning with the ATC, in line with the position. 180 o "Rotary ATC devices can be used horizontal machine, can also be used for vertical machining centers.
2. 2 ATC head-turret installed
With rotating CNC machine tool often used such ATC devices, with a few turret head spindle, each with a spindle on both knives, the first tower interim process can be automatic tool change-realization. The advantage is simple structure, tool change time is short, only about 2 s. However, due to spatial constraints, the number of spindle can not be too much, usually only apply to processes less, not to high precision machine tools, such as the NC drill, such as CNC milling machine. In recent years there has been a mechanical hand and the turret head with a knife for the automatic tool change ATC devices, as shown in Figure 2.3. It is in fact a turret head ATC, and the knife-ATC device combination. The principle is as follows:
5 turret on the first two tool spindle 3 and 4, when using the tool spindle 4 processing tool, the manipulator 2 will be the next step to the need for the tool does not work on the tool spindle 3 until after the completion of this process , the first rotary turret 180 o, ATC completed. ATC most of their time and processing time coincidence, the only real tool change time turret transposition of the first time, this approach mainly used for ATC and NC NC drilling file bed.
2. 3.Daidao system for the automatic tool change
Figure 2.4 shows the knife and the whole machine tool CNC machine tools for the appearance of Fig.
? Figure 2.5 shows the knife and split-type machine to the appearance of CNC machine tool plans.
At this point, knife storage capacity, a heavier tool can, and often additional transport unit to complete the knife between the spindle and cutting tool transport.
